“…Our finding is congruent to the 2:1 male-to-female ratio reported by 2 other studies that included 51 patients and 20 patients respectively. 5,6 Only 1 study with 29 patients presented a 1.6:1 ratio in favor of females. 28 All other reports with different gender ratios showed no clear tendency and were carried out with smaller numbers of patients.…”

“…3,4 Further studies demonstrated that, even in patients with local spillage, nephrectomy alone was sufficient. 5,6 In 1973, Joshi et al, Fu and Kay, and Walker and Richard [7][8][9] were the first to report 2 local recurrences in patients with MN. In 1981, GonzalezCrussi et al described the first patient with MN who had a metastasis to the lung 10 ; and metastases to the liver, 11 brain, 12,13 and heart 14 were reported subsequently.…”

BACKGROUNDSurgery alone is the appropriate first‐line treatment for patients with mesoblastic nephroma (MN). Nevertheless, there are reports of local recurrences and metastasis, especially in the cellular subtype. The authors evaluated the outcome of patients with MN who were enrolled in either the International Society of Pediatric Oncology (SIOP) 93‐01/GPOH or the SIOP 2001/GPOH Nephroblastoma Study and Trial.METHODSIn total, 50 patients with MN were analyzed. Eleven patients were suspected antenatally of having a renal tumor. The median age at diagnosis was 18.5 days. Central pathologic review was performed for all specimens. The median observation time was 4.2 years.RESULTSForty‐five patients underwent initial surgery. Five patients older than 6 months received preoperative chemotherapy. Twenty‐nine tumors were classic MN, and 21 tumors were cellular MN. Nine patients had a Stage III MN, 5 of those patients had tumor ruptures, and 8 had positive surgical margins. After they underwent nephrectomy, 40 patients received no further treatment. For the entire group, event‐free survival (EFS) (94%) and overall survival (OS) (95%) were excellent. Patients with a cellular MN, patients with age 3 months or older, and patients with Stage III MN had lower EFS. Three patients developed recurrent disease, and 2 of those patients died. Metastases to the brain, lung, and liver were observed in 1 patient.CONCLUSIONSRadical nephrectomy with accurate surgical‐pathologic staging is the standard of care for children with MN. Nonetheless, a subgroup of patients with MN (Stage III cellular MN in patients age 3 months or older) tends to develop recurrences more often. Further prospective studies will be needed to verify this finding and should help determine whether these patients may benefit from adjuvant therapy. Cancer 2006. © 2006 American Cancer Society.

ABSTRACT ABSTRACT ABSTRACTWilms' tumor (WT) represents 6% of childhood cancers. Recent advances in molecular biology have significant implications for the clinical management. A dramatic improvement in overall cure has resulted from the adoption of multimodality treatment during the past few decades. National Wilms' Tumor Study (NWTS), and the Société Internationale d'Oncologie Pédiatrique (SIOP) have laid down the guidelines for standardized treatment of WT, though differing in the diagnostic and therapeutic approach. Both these groups currently aim at intensifying treatment for patients with poor prognosticators while appropriating the therapy to reduce long-term complications for those with favorable prognostic features. Challenges faced in developing nations include poverty, malnutrition, ignorance, and presentation in advanced stages coupled with limited facilities that are necessary for total management of these cases. In this article, we have discussed our approach to deal with patients with nephroblastoma, reviewed the literature on the current management strategies and the long-term outcome. Most countries have adopted the NWTS protocols, while others especially in Europe, South America and some Asian countries follow the SIOP regimen. Both have their advantages and weaknesses and maynot necessarily be suitable to the setup in developing countries. We have discussed the controversial issues in the management of WT including the timing of biopsy, type of biopsy, investigative approach, role of chemotherapy / radiotherapy, management of bilateral Wilms' tumor and parenchymal sparing renal surgery. Despite deviating from NWTS at various points, the overall results have remained satisfactory. Thus, developing countries might adopt their own protocols depending on the prevalent situations and facilities available to them to treat such patients.
